Product Description

Our National Match style rear sight is designed to fit into the dovetail of GI pattern 1911 pistols.  Its extra thick serrated blade is .315" tall for compatibility with new production Colts, and features a .140" wide U notch. User installable (with some hand fitting), no machining required.  The newly revised design includes a more rounded profile and additional edge chamfers to improve comfort for handling and carry. 

  • FITS: GI pattern dovetails such as Colt and Springfield Armory with GI pattern sights.
  • Compatible with: front sights of .175-.185" height.  
Is direct replacement for Colt, Springfield Armory, and other 1911s with GI/Milspec rear dovetail. Compatible with factory front sight on Colt 1991A1, new production Series 70 reproduction, and Springfield Armory Milspec models, and does not affect point of impact.
**Be aware that older production Colts with the very low GI style "thumbnail" front sight will require a taller front sight to work with this rear. Machining of the slide is typically necessary and recommended to install a modern dovetail front sight. We neither recommend nor know of any options for traditional style staked on front sights. High profile staked on fronts were bad when we had them in the 80's - they fell off a lot due to the extra weight/inertia from the mass - and they are not any better of any option now that we have dovetailed fronts available.

  1. Impressed with the sight 5 Star Review

    Posted by on 1st Dec 2013

    Had a gun smith remove my damaged original rear sight on my M199A1 & replaced with the 10-8 NM Rear sight. I actually prefer the new sight to the original one. Very impressed with 10-8's service!

  2. Much Improved Sight Picture 5 Star Review

    Posted by on 1st Dec 2013

    Put this on my RIA CS, replacing the GI sight. Had to do a little filing to get it to fit, but looks great. Have a FO on the front,the sight picture for my aging eyes is now much better and aquisition is much faster.
    Very happy with the product

  3. Great sight 5 Star Review

    Posted by on 21st Nov 2013

    Installed on an Auto Ordnance 1911A1 with a Trijcon front sight. Fast to get on target and improved accuracy.

  4. Great upgrade for rear sight. 5 Star Review

    Posted by on 3rd Jul 2013

    I installed this rear on a Para Expert. It works out perfectly with the FO front that came on that gun.

  5. 'Older eyes' but still carry daily 4 Star Review

    Posted by on 13th May 2013

    The sights are great for range use on a 5" Colt

    Availability of an occasional run of wider notch might suit folks whose vision needs all the help it can get.

  6. 10-8 NM rear sight 5 Star Review

    Posted by on 6th Mar 2013

    Impressed with the quality of manufacture, and the small amount of fitting required. Target aquisition is much faster, and my shooting greatly improved. I wish someone would make a gold bead front for use with older Colt's with the small tenon, won't mill my slide. How about it 10-8?

  7. NM style 1911 rear sight 5 Star Review

    Posted by on 6th Mar 2013

    Service and delivery worked out fine.
    Visual and tactile review of part was very satisfactory.
    Please receive my very satisfied report with the qualification that this rear sight has not yet been installed and used. I did "jerry rig" it with tape to check the sight picture and remained enthusiastic and satisfied.

  8. Awesome 5 Star Review

    Posted by on 14th Feb 2013

    Very nice sight. Serrated with the wide notch is great. I use wide .140 notches on my Fn's, Glocks, and now 1911's. My only complaint is 10-8 does not offer a stake on .090 width plain black serrated front sight to match. It would save on shipping. I will be ordering another soon for one of my other 1911's.

  9. A MUST 5 Star Review

    Posted by on 22nd Nov 2012

    this is the best upgrade to a rear sight

  10. Excellent product 5 Star Review

    Posted by on 19th Jul 2012

    The 1911 NM Rear Sight is excellent quality. It is much sturdier than the factory sight and has a wider aperture, making it easier to find the front sight. It took a minor amount of fitting with a file to get it onto the slide, but installation was reasonably simple. I tested it immediately after installation and it simplifies the sight alignment/sight picture problem significantly over the factory sights.
